Yountville
Dubbed the best damn party of the year, this boot-stomping hoedown kicks off the harvest season. More than an event, Harvest STOMP® is a heartfelt toast to Napa Valley’s agricultural heritage and an inspired call to continue safeguarding its future.
​
This extraordinary evening raises funds for two of the Valley’s most vital viticultural nonprofit organizations: the Napa Valley Grapegrowers and Napa Valley Farmworker Foundation. Fifth-generation grape growers—Kendall Hoxsey Onysko and Morgaen Hoxsey Pickett—will host the not-to-be-missed 18th annual Harvest STOMP®.
​
So, dust off those cowboy boots, grab your favorite hat, and get ready to raise a glass, raise a paddle, and share in an unforgettable night that celebrates the very spirit of Napa Valley.
18th annual harvest stomp
